May a Preferred Customer upgrade to a Distributorship and keep all their referred Preferred Customers?

Yes, if a PC wants to become a distributor and wants to keep all the referred PCs they would print the Distributor Enrollment form, fill out all the required fields and before faxing that application to Distributor Support they would write a note on the application specifying that they wish to upgrade from a PC to Distributor. By doing so, they get to keep the same ID number and also keep all the PCs they referred.
